This binding covers more and with that there are a few more properties that the max31335 on it's own doesn't have (e.g. the clock consumer, the ability to have different i2c addresses). Binding wise I could probably roll all of the max31335 into this max313xx binding.

But I won't take a separate driver. Everything would be better if Analog
was sharing the datasheets...
